In a list of the “10 Biggest Unsolved U.S. Terrorism Cases,” Parapolitical counts five attacks of greater severity than this week’s marathon bombing that were never solved. Topping that list is the 1920 Wall Street bombing. Ninety-three years after the attack that killed 38 at J.P. Morgan, no one has taken credit.
In close second is the 1975 bombing of New York’s La Guardia airport, an attack that killed 11. The 1916 San Francisco Preparedness Day bombing and the 1933 bombing of United Airlines flight 247 both also had death tolls at, or approaching, double-digits. Neither case has been closed.
Aside from the Boston Marathon attack, the most recent unsolved terrorist bombing in the U.S. was the 1985 murder of Alex Odeh in Santa Ana, California, an attack that resulted in 3 casualties.
Alex Odeh, a Palestinian Christian immigrant to the United States working as regional director of the Arab-American Anti-Discrimination Committee, was killed in a bombing of the group’s offices as he was preparing to leave to speak at a Fountain Valley synagogue. Though no one has claimed responsibility for the murder, the Jewish Defense League is thought to be responsible. The FBI identified three suspects in the attack, all of whom left the United States for Israel after the bombing.
According to the FBI’s website, a $1 million reward is still being offered for information leading to the arrest and conviction of Odeh’s killers.
